Abstract
The utility model relates an electronic acoustic product, specifically to a full tone coaxial co-phase loudspeaker. Inside the full tone coaxial co-phase loudspeaker, a spiral shaped magnet is located in the ring part of the loudspeaker, the magnet is clamped by a yoke iron, a magnetic column is located in the middle of the loudspeaker, a sound loop and a sound loop frame are wound outside the magnetic column, the upper part of the yoke iron is provided with a centering supporting sheet, a basin frame and a paper basin, the center position of the paper basin on the upper part of the magnetic column is a piezoelectric component and a spherical top shaped high voice phonation film concurrently used as a dust proof cover. The utility model has the following advantages: simple structure, perfect function, full frequency playing effect, the sound is clear, the loudness is enough, the hierarchy sense is distinct, and the directionality and permeability are good.
Description
The utility model relates to a kind of electronic audio product, the coaxial homophase loud speaker of specifically a kind of whole tone.
In the prior art, audio amplifier in the common sound equipment is to combine with bass, high pitch loudspeaker, or the divergence type audio amplifier that combines with bass, middle pitch, high pitch loudspeaker, its objective is to reach whole tone playback effect frequently, satisfy the requirement of people's audition, but this audio amplifier on tonequality, tone color definition and each reducing property, all exist difference, it is unintelligible sound usually to occur, dynamics is not enough, and stereovision is not distinct, and directionality is poor, permeability is bad.In addition, common woofer be narrow-band design, if install at grade, then, cause the phase difference problem because of point of articulation does not produce high pitch at grade fast to the then late phenomenon that reaches of intelligent's ear, bass at audio amplifier medium and low spectrum loudspeaker and high pitch loudspeaker.
Task of the present utility model is to overcome above-mentioned weak point of the prior art and a kind of stereovision distinctness, the coaxial homophase loud speaker of whole tone that directionality is strong is provided.
In order to realize above-mentioned task, the utility model provides a kind of new technical solution: the coaxial homophase loud speaker of this whole tone, critical piece is a magnet, yoke, the basin frame, cone, centring disk, voice coil loudspeaker voice coil, sound ring frame, the high pitch tibial membrane, magnetic post and piezoelectric element, the magnet of the rotation bodily form is positioned at the ring portion of loud speaker, magnet is the yoke clamping, the magnetic post is positioned at the middle part of loud speaker, voice coil loudspeaker voice coil and sound ring frame are around in outside the magnetic post, the yoke top is provided with centring disk, basin frame and cone are positioned at magnetic post top, the center of cone is the ball top form height sound tibial membrane of piezoelectric element and double as dust cap.
The utlity model has following advantage: simple structure, perfect in shape and function, whole tone be result of broadcast frequently, and sound is clear, dynamics is sufficient, the stereovision distinctness, and directionality, permeability are good.
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing and concrete execution mode essentiality content of the present utility model is described in further detail.
This complete coaxial homophase sound loud speaker, critical piece is magnet (1), yoke (2), basin frame (3), cone (4), centring disk (5), voice coil loudspeaker voice coil (6), sound ring frame (7), high pitch tibial membrane (8), magnetic post (9) and piezoelectric element (10).The magnet (1) of the rotation bodily form is positioned at the ring portion of loud speaker, magnet (1) is yoke (2) clamping, magnetic post (11) is positioned at the middle part of loud speaker, voice coil loudspeaker voice coil (6) and sound ring frame (7) are around in outside the magnetic post (9), yoke (2) top is provided with centring disk (5), basin frame (3) and cone (4), and the center that is positioned at magnetic post (9) top, cone (4) is the ball top form height sound tibial membrane (8) of piezoelectric element (10) and double as dust cap.This loud speaker is the same with traditional electrical dynamic formula loud speaker principle, is that voice coil loudspeaker voice coil (6) is placed in the high-intensity magnetic field, as the audio voltage electric current make during by voice coil loudspeaker voice coil (6) its produce electromotive force promote in bass cone (4) make it send middle bass.High pitch is partly for adopting piezoelectric element (10) as the pronunciation source, and piezoelectric element (10) when being subjected to electric field action deformation vibration takes place and promotes ball top form height sound tibial membrane (8) and send high pitch.Owing to adopted this structure, this loud speaker can be emitted the whole tone yupin effect of 20Hz-200KHz in coaxial same-phase last time.
